Cameron Park rules that affect a attached adu
In Cameron Park, an attached unit shares a wall and utility runs with your main home, which can cut trenching and site costs — useful on tighter lots where a fully detached build would crowd the yard. The El Dorado County Planning & Building Department reviews it as new attached square footage.
Local permitting: Cameron Park permits through the El Dorado County Planning & Building Department. Larger lots comfortably fit a full detached ADU; many parcels are on septic, and the Cameron Park Airport overlay can affect a small subset of properties, which we verify during feasibility.
That's the attached adu-specific picture. For the full El Dorado County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our attached adu page.
